3O2( g)⇌2O3( g)

for the above reaction at 298 K, Kc is found to be 3.0×10-59. If the concentration of O2 at equilibrium is 0.040 M then concentration of O3 in M is

Options:

Answer:
D
Solution:

Kc=3.0×10-59
O2g=4×10-2.
The given reaction 3O2g⇌2O3g
Kc=product of molar concentration of productsproduct of molar concentration of reactants=O3g2O2g3 

Put all the given values in the expression of Kc

3.0×10-59=O3g24×10-23
⇒[O3(g)]2=3.0×10-59×(4×10-2)3
⇒O3g2=192×10-65
Hence, the concentration of O3 = 4.38×10-32 M
